I don't think I can say enough about J. Crew flannels. I buy at least one of these every season, but the current red and black pattern is my favorite, yet.
These shirts wash well (no pilling or shrinking) and the slim fit is a perfect spin on the classic "boyshirt" style. I love this particular version, where the buttons end midway down the shirt. For some reason it feels a little dressier, more like a tunic than a regular old flannel.
Easily dressed up or down, these shirts are a cold weather fashion staple, for sure. While I won't always shell out the cash for J. Crew products, these flannels are worth their weight in gold.
